Adding new chicks....

Hi all, I've been reading all about your experiences and am so thankful this forum is here!

I have 6 chicks in a brooder downstairs... and am adding 4 more on Tuesday. Both groups of chicks were born the same day. I'd like to add the newcomers in with the original 6.

My plan is to get a bigger brooder (I bought a large dog cage) and put all 10 in there at the same time. I thought it would break up the original chick's pecking order being in a new place and give the others a better chance to assimilate.

Does my line of thought make sense? Or do I have to divide up the larger cage and let them watch each other through wire?

I have decided to go with the huge dog kennel (larger!) and put all 10 in together. Those EE's play rough and I didn't want them to have the upper hand...so they'll all go somewhere new. Hope it works!

I do see some dominant EE's by the way. My flock outside better watch these guys!
